The Andrew W. Mellon Foundation Art Museum Staff Demographic Survey
The Andrew W. Mellon Foundation, in partnership with the Association of Art Museum Directors (AAMD) and the American Alliance of Museums (AAM), has announced the results of the first comprehensive survey to assess the ethnic and gender diversity of the staffs of art museums across the United States. Undertaken to replace anecdotal evidence with hard data, the survey provides the museum field with the first statistical baseline against which progress can be measured. Art Museum Staff Demographic SurveyAmong its chief findings, the survey documented a significant movement toward gender equality in art museums. Women now comprise some 60 percent of museum staffs, with a preponderance of women in the curatorial, conservation and education roles that can be a pipeline toward leadership positions. The survey found no such pipeline toward leadership among staff from historically underrepresented minorities. Although 28 percent of museum staffs are from minority backgrounds, the great majority of these workers are concentrated in security, facilities, finance, and human resources jobs. Among museum curators, conservators, educators and leaders, only 4 percent are African American and 3 percent Hispanic
Pre- and postprocessing techniques for determining goodness of computational meshes
Research in error estimation, mesh conditioning, and solution enhancement for finite element, finite difference, and finite volume methods has been incorporated into AUDITOR, a modern, user-friendly code, which operates on 2D and 3D unstructured neutral files to improve the accuracy and reliability of computational results. Residual error estimation capabilities provide local and global estimates of solution error in the energy norm. Higher order results for derived quantities may be extracted from initial solutions. Within the X-MOTIF graphical user interface, extensive visualization capabilities support critical evaluation of results in linear elasticity, steady state heat transfer, and both compressible and incompressible fluid dynamics
Mechanical effect of van der Waals interactions observed in real time in an ultracold Rydberg gas
We present time-resolved spectroscopic measurements of Rydberg-Rydberg
interactions in an ultracold gas, revealing the pair dynamics induced by
long-range van der Waals interactions between the atoms. By detuning the
excitation laser, a specific pair distribution is prepared. Penning ionization
on a microsecond timescale serves as a probe for the pair dynamics under the
influence of the attractive long-range forces. Comparison with a Monte Carlo
model not only explains all spectroscopic features but also gives quantitative
information about the interaction potentials. The results imply that the
interaction-induced ionization rate can be influenced by the excitation laser.
Surprisingly, interaction-induced ionization is also observed for Rydberg
states with purely repulsive interactions

Management practices and sugar end potatoes
French fries processed from sugar end potatoes become
undesirably dark on one end while remaining
light on the other (fig. 1). The darkening is usually
caused by a higher concentration of reducing sugars
in the darkened end of the fry strip. Sugar ends are
associated with tubers that are pointed on the stem
end but also occur in ideally shaped tubers.
"Translucent end," "jelly end," and "sugar end"
describe the same physiological tuber problem. Translucent
end tubers with high levels of sugars develop
jelly end rot after progressive tissue breakdown
occurs. The Russet Burbank variety is particularly
susceptible to sugar end formation when subjected to
water and heat stress
